1'0 all whom, it may concern:

Be it known that I, WILLIAM POTTER, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Combination Draft-Excluders and Locks, of which the following is a specification, such aswill enable those skilled in the art to which it appertains to make anduse the same.

The object of this invention is to provide an improved draft-preventerfor doors and windows which is easily operated and which effectuallyexcludes air from a door or win dow provided therewith, a further objectbeing to provide a device of this class which serves also as a lock andWhich is simple in construction and operation, comparativelyinexpensive, and well adapted for the purpose for which it is intended.

As is well known, doors and windows, as well as the frames thereof, arefrequently warped or uneven, due to carelessness of con- 'str'uction orto climatic influences, and in the case of the latter windows and doorsare frequently rendered so tight as to be inoperative but bymeans of myinvention the sash runs of window-frames may be made very loose, therebypreventing binding when swollen, as may also door-frames, and stillpermit of the total exclusion of draft.

My invention is fully disclosed in the following specification, of whichthe accompanying drawings form a part, in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe views, and in which- Figure 1 is a partial face view of the innerside of a window-frame and showing a sash provided with my invention;Fig. 2, a section on the line 2 2 of Fig. 1; Fig. 3, a section on theline 3 3 of Fig. 1; Fig. 4, a'partial edge view of the sash; Fig. 5, avertical section taken on the line 5 5 of Fig. 2; Fig. 6, a partialouter view of a door provided with my invention; Fig. 7,- a section onthe line 7 7 of Fig. 6 Fig. 8, a section on the line88 of Fig. 6, andFig. 9 a detail of the construction shown in Fig. 6.

In Figs. 1 to 5, inclusive, I have shown a vertically-movable sash a,mounted in a frame I) and showing a space between the same at eitherside of the sash, and arran ed in a vertical slot a in the edge of thesas a is a bar (1 which extends the full length of r the sash, and onthe inner face of the sashstile is a plate a, to which is pivoted alever a as shown at a, and the pivot a carries an eccentric-pin aarranged normally in the horizontal axis of said pivot. Arrangedcentrally of the bar a is a tube 0, which extends into the sash a and isprovided with slots 0 into which the bar a passes, and within the tube 0is a supplemental tube 0 through which the bar a passes and in which itis engaged, said tube 0 having a projecting head 0 which in its lockedposition extends into a cup or recess 6 in the frame I), and said framemay be provided witha number of these cups 6 if desired, therebyenabling said sash to be locked in a corresponding number of positions.Also slidably mounted in the tube a is a block d, provided with a headedpin (P, which is slidably engaged-by the tube 0 and a coil-spring d isarranged between the tube 0 and the block 01, said spring d serving toforce the said members apart, and the eccentric-pin (1 passes into theblock d and serves to operate the same inwardly and outwardly. Securedin the sash a above and below the tube 0 are tubes e, provided withslots 6 into which the bar a is adapted to pass, and slidably mounted inthe tubes e are supplemental tubes a which are secured to the bar a bypins 6, and said supplemental tubes 6 are normally forced outwardly bymeans of strong spiral springs a which bear against the bar a and, aswill be seen, when the lever a is moved in one direction the bar a isforced outwardly by the springs e against the frame a, and said baradapts itself to any irregularity between the sash and frame, and thesash is also forced against the opposite side of the frame a, andthereby closes the openings therebetween, and when the lever a is movedin the opposite direction the bar a is drawn inwardly against thesprings e and flush with the edge of the sash, and said sash may bereadily moved, these positions of the bar a being clearly shown in Figs.1 to 5, inclusive. If the lever a be moved to the locking position(indicated in dotted lines in Fig. 1) and the tube 0 be out of line witha cup 6 the pin (Z2 enters the said tube c ,and thereby permits the bara to engage the frame a, and if the tube 0 be in line with a cup 6 theplay on said pin d permits the said tube or the head 0 thereof to enterthe said cup, and the window is securely locked.

In Figs. 6 to 9, inclusive, I have shown my invention adapted to abath-room or toilet- IIO door, said door being indicated by thereference character it and the frame thereof by the reference character11, the locking devices being similar to those described in the window,with the exception that the eccentric-pin a passes entirely through thedoor and is held in a telescopic recess h, eccentrically secured in aplate It", pivoted centrally thereof in a casing it, said casing 7Lbeing secured to the outer side of the door h and is provided with asegmental opening 71/5, at which either of two inscriptions on the plateIt may be read, said plate being shown in detail in Fig. 9, and, as willbe understood, the rotation of the lever a to lock or open the doorturns the plate h correspondingly.

It will therefore be seen that by means of my invention sashes and doorsout of parallel with their frames may be made weather and dust tight,for the reason that the bar (1 being centrally mounted andspring-actuated, upon touching the frame at either of its endsimmediately finds the plane of said frame, and a sash so provided alsofinds the plane of the frame at the side opposite the bar a and rattlingis prevented, and the use of weatherstrips, stormsash, and sash-locks isobviated, and if'sash-weights are not employed my invention willeffectually lock said sash in any desired position. Doors so providedwill exclude all offensive odors and. gases.

In Figs. 1 and 7 I have shown a coil-spring 70, secured at 7c to theplate a and at k to the pivot a of the lever a and serves as acounterbalance for the springs a in the withdrawal of the bar atherefore making the device easily operative by a child.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A draft-eXcluder for doors, sashes and the like, comprising a barmovable in a recess in said door or sash and adapted to bear against theframe thereof, a tube secured in said door or sash, a supplemental tubeslidable therein and provided with slots in the opposite sides thereofthrough which said bar passes and said bar being provided with a recessadapted to receive the end of said supplemental tube, a block slidablein said firstnamed tube, a spring between said block and saidsupplemental tube and adapted to force said supplemental tube outwardly,devices for moving said block backwardly and forwardly in saidfirst-named tube, coil-springs mounted in said door or sash adjacent tosaid tube and adapted to force said bar outwardly, substantially asshown and described.

2. A draft-excluder for doors, sashes and the like, comprising a barmovable in a recess in said door or sash and adapted to bear against theframe thereof, a tube secured in said door or sash, a supplemental tubeslidable therein and provided with slots in the opposite sides thereofthrough which said bar passes and said bar being provided with a re cessadapted to receive the end ofsaid supplemental tube, a block slidable insaid firstnamed tube, a spring between said block and said supplementaltube and adapted to force said supplemental tube outwardly, devices formoving said block backwardly and forwardly in said "first-named tube,coil-springs mounted in said door or sash adjacent to said tube andadapted to force said bar outwardly, and said devices comprising a levermounted on the face of said door or sash, and a pin eccentricallymounted on said lever and slid ably mounted in said block, substantiallyas shown and described.

3. A draft-eXcluder and lock for doors, sashes and the like, comprisinga bar movablein a recess in said door or sash and adapted to bearagainst the frame thereof, springs for forcing said bar outwardly, atube arranged centrally of said springs, a supplemental tube slidable insaid first-named tube and provided with slots in the opposite sidesthereof through which said bar passes and in which it is engaged, saidbar being provided with a recess to receive the end of said supplementaltube, devices in operative connection with said. supplemental tube formoving the same inwardly and outwardly, means for moving saidsupplemental tube outwardly a distance greater than the movement of saidbar and a recess in said frame adapted to receive said supplemental tubeand thereby lock said door or sash, substantially as shown anddescribed.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 13th day of May,1905.

WILLIAM POTTER.
